To' all whom it may concern Be it known that we, Josemi WV. LUNDAHL,

. nvcitizen of the United States, and OSCAR Anvin EKs'rnoM, n subjectofthe King of' Sweden, andl residents,- "respectively, of'

Thornnston, in the county of Litchfield and State 'of Connecticut, andLitchfield, Flute' ville, in the county of Litchfield and State of.Connecticut, have invented a new and: Improved Automatic Ignition Systemfor" GasLights, of which the following is a full,

f "5.111 thencoo .illustrate-'one em odiment of^theimventio;, v

clear, and exact description.

. ,This invention relates to ignition and gals' controlled systemsespecially adapted "foruse in connect-ion with automobile lamps,Awhereby the driver can light the lamps bya l single controller Withoutmoving from the sent, and while the system is useful inthis`eonnectionit isto be understood that itfis applicable for house andother lighting systemsw'here the burners areftobe lighted. from; aremote point, 1

The .invention Ihas for its general object to improve and simplify theconstruction' and operation of combined gas controlling" and i nitinordevices so as to be reliable and.

efficient in use, comparatively*inexpensive to manufacture and installand composed of comparatively few parts.

Another object of the invention is the prou vision of the make-and-brenkdevice which operates simultaneously with the gas valve for opening andclosing the primary circuit in rapid succession, so as to produce a hightensioncurrentin the secondary circuit for generating igniting sparks atthe gas burner or burners, said makemnd-'break device thereby dispensingwith th-e usual vibrator nt the induction coil.

Another object of the invention is to so' mount the make-and-breakdevice that the same will be actuated by the handle that op crates theneedle valve, the make-and-break device including a toothed ContactWheel and a spring Contact cooperating with the teeth, whereby themovement of the teeth past the spring contact will produce a successionof current impulses through the primary circuit.

An additional object of the invention is the provision of a novelignition device in-y cluding electrodes which are movably mounted withrespect to each other so that Specification of Letters Patent.v
